NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Apr. 1, 1913.

Application ler .T uly 26, 1912. Serial No. 711,695.

To all whom t may concern:

Be it known that I, HERBERT NICHOLSON, a citizen of the United States of America, and a resident of Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Non- Refillable Bottles, of which the following is a specification. f

This invention relates to that class of bottle Stoppers in which an automatically operating valve is employed to prevent a refilling of the bottle after the original contents of the same have been partly or wholly removed; and the present improvement has for its object to provide a simple, durable and efficient structural formation and combination of parts adapted to afford a very effective seal against a refilling operation, and at the same time permit a ready and free outflow of the liquid contents of the bottle, all as will hereinafter more fully appear and be more particularly pointed out in the claim.

In the accompanying drawings Figure 1, is a central sectional elevation of a bottle stopper embodying the present improvement. Fig. 2 is a detail horizontal section, on line -m, Fig. 1.

Similar reference numerals indicate like parts in both views.

Referring to the drawings, 1 represents the neck portion of a bottle having the usual cylindrical bore for the reception of valve or stopper mechanism, as usual in the present class of non-rellable bottles. And'said bottle neck is preferably formed near its lower end with an inturned shoulder 2 against which the hereinafter described valve housing has abutment.

3 is the valve housing above referred to, and preferably comprising a counterpart pair of cup shaped members, the skirt portions of which are adapted to fit the bore of the bottle neck, while the head portions thereof are a skeleton form having central guide hubs for the stem of the valve now to be described.

4 is a valve head having its seat on the uppermost of the cup shape members abo-ve described, to normally close the passages through said members resulting from the skeleton form of the head thereof.

5 is the depending guide stem by which the valve head 4 is guided in its rectilinear opening and closing movements and to such end said stem passes through central guide orifices in the hub portions of the aforesaid said bail and the lower end of the valve stem 5, and adapted to normally valve in a closed position. Y 8 is a baiiie member of the hold the present construction, and by means of which any tampering with the valve to render it inoperative is effectively prevented. Said batlle member comprises a detail construction as follows 2 9' is a cylindrical skirt portion of the baflie member formed at its lower end with a marginal flange or rim 10, ada ted to t the bore of the bottle neck, and a apted to carry the fastening means, hereinafter described, by which the present valve or stopper mechanism, is secured in place. In the preferred construction shown in Fig. 1, the lower end of the skirt portion 9, lits into a marginal recess formed therefor in the upper end of the upper cup shaped member of the valve` housing 3, before described.

11 are a series of lateral orifices of any usual shape, formed in the cylindrical skirt portion 9 above the aforesaid marginal flange or rim 10, and adapted to aord a means, of communication between the interior of the skirt portion 9 and the annular space existing between the periphery of the upper part .of said skirt and the bore of the bottle neck, as shown. Such construction provides a tortuous way for the flow of the Huid, and through which it would be very difficult to introduce a wire or the like, to tamper with the valve head 4.

12 is an imperforate headformed inte grally with the skirt portion 9, and in connection therewith constituting a protecting cap for the valve head 4, aforesaid, to limit and protect the same in its movements.

13 is a spring lock of any usual form, and disposed in opposed recesses in the adjacent surfaces of the marginal flange 10 above described, and in the inner face of the neck of the bottle, as illustrated in Figs. 1 and 2, and adapted to lock the parts in assembled relation and require a fracture of the parts in eecting a disassemblage.

Having thus fully described my said invention what I claim as new and desire to secure by Letters Patent, is

In a bottle stopper of the type described, the combination of a valve housing fitting the neck of a bottle and consisting of a pair of cup-shaped members, each comprising a cylindrical shell and a central hub disposed at the upper end of the shell and integrally connected thereto by skeleton arms, a valve having its seat on the upper end of the upper Cup-sha ed member, a guide stem carried by sai valve and having guiding engagement with the hubs aforesaid, means for normally holding the valve to its seat, the same comprising a depending bail oonnected to the .open bottom of .the lower oupshaped member and `a spring attached to said ibail .and to the lower end of the guide stem, and .a baiiie member disposed outside the cup-shaped members and consisting of a cylindrical shell formed With a closed top, a peripheral flange at its lovver end itting the bore of av bottle neck and providing an annular cavity above said flange, and a L series of oriliees connecting said annular `cavity With the interior of said shell, the valve aforesaid having its movement in the interior of said shell.

Signed at Chicago, Illinois, this 25th day of July 1912.
